I cannot seem to add anything to the header section without crashing my mobile menu causing it to display like a site map instead of correctly.
I am simply trying to add the following to the html_header.php file in /includes/templates/responsive_classic/
HTML Code:
  } else if ( $_SESSION['layoutType'] == 'full' ) {
    echo '';
  } else {
    echo $responsive_default;
  }
}
?>
<link href="cc-slideshow-be4ffe51/css/slideshow.css" rel="stylesheet">
<script>document.createElement( "picture" );</script>
<script src="cc-slideshow-be4ffe51/js/picturefill.js" class="picturefill" async="async"></script>
<link rel="stylesheet" href="cc-slideshow-be4ffe51/css/main.css">
<script src="cc-slideshow-be4ffe51/js/jquery-1.8.2.min.js"></script>
<script src="cc-slideshow-be4ffe51/js/revolver.min.js"></script>
<script src="cc-slideshow-be4ffe51/js/slideshow.js"></script>
  <script type="text/javascript">document.documentElement.className = 'no-fouc';</script>
  <link rel="stylesheet" type="text/css" href="//maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" />
<?php // ZCAdditions.com, ZCA Responsive Template Default (EOF-addition 2 of 2) ?>
<?php
  $zco_notifier->notify('NOTIFY_HTML_HEAD_END', $current_page_base);
?>
</head>

<?php // NOTE: Blank line following is intended: ?>

Anyone know why or maybe tell me where I should add it instead. I need it in the header to use my special banners.

Thanks
